![]() Device outputs can sink and source 430 mA and 290 mA respectively. The outputs can be driven by two dedicated logic signals or, alternatively, only one logic signal by connecting the two inputs together. The L6390 is a half-bridge driver with several functions such as externally adjustable deadtime, interlocking, smart shutdown (patented), fault comparator and a dedicated high-performance op-amp for advanced current sensing. This feature is achieved by means of a high voltage DMOS synchronously driven with the low side gate driver. The devices have a driver current capability best suited for home appliance motor driving ratings, and they are also equipped with patented internal circuitry which replaces the external bootstrap diode. This device can be used in all applications where high voltage shifted control is necessary. From Electronics-lab site describe that t he L6390 is a high voltage half-bridge gate driver. ![]() Circuit schematic like in Figure 1 above is High Voltage Half-Bridge With Current Feedback Using L6390.
